Call accounting devices and printers allow the system manager to print
call reports. The call accounting device or printer connects directly to the
primary processor module in the primary carrier. See “Call Reporting
Devices (SMDR)” on page 7-7 for more information.
Doorphones allow visitors to alert up to five extensions at once by
pressing a button on the doorphone; the person who answers a
doorphone call can then use the phone to speak to the visitor at the
doorphone. The equipment controller supports up to two proprietary
doorphones, which can be installed indoors or outdoors. A doorphone is
especially useful for providing access to offices or departments after
hours. For example, you can install a doorphone outside your building
entrance to allow visitors to alert telephones inside the building when the
receptionist is not there and the front door is locked.
Loudspeaker paging systems allow you to broadcast a message over a
large area, by connecting the paging system directly to the PAGE jack on
the primary processor module. The equipment controller supports all
AT&T paging systems. For information on how to use a loudspeaker
paging system with the equipment controller, see page 6-17.
Music-on-hold systems allow you to play recorded music to callers
while they are on hold, by connecting the music-on-hold system to the
primary processor module. The equipment controller supports the AT&T
Magic on Hold system and most models from other manufacturers.
Extra alerts are strobes, lights, chimes, horns, or bells that light or ring
when calls come in. For example, you can use an audible alert (chime,
horn, or bell) to replace a phone ring in a noisy area, such as a factory.
Similarly, you can use a visual alert (strobe or light) to replace a phone
ring in a quiet area, such as a library.
Electromagnetic Interference (EMI) filters allow you to block “noise”
generated by a nearby radio station, as well as most electrical devices.
The equipment controller supports the AT&T Z300A EMI Filter.
Uninterruptible Power Supply (UPS) allows full equipment operation
during a power failure. The equipment controller supports the AT&T
360VA UPS.
In-Range Out-of-Building (IROB) protectors are required to prevent
electrical surges from damaging your equipment when phones are
installed in another building, but on the same continuous property. The
equipment controller supports the AT&T IROB protector, which provides
coverage over a distance of 3,000 feet for standard phones and 1,000
feet for MLS- and MLC-model phones. (For installation instructions, refer
to the booklet packaged with the IROB protector.)
